After anchoring at Socorro, one of the four islands that make up the Revillagigedos archipelago, the Shark Men catch their first male of the expedition—a 6½-foot silky shark. The science team is excited, as silkies are one of the top five species caught as bycatch in the region, so they want to tag as many as they can. Meanwhile, the seas are getting rougher and the mother ship is having serious electrical issues that threaten the entire mission.
